THOMAS F. DWYER, OF BROOKLYN, NEW YORK.

HINGE FOR WINDOW-SHUTTERS.

SPECIFICATION forming part of Letters Patent No. 783,184, dated February 21, 1905.

Application filed August 9; 1904. Serial No. 220,054.

To a whom, it may concern.-

Be it known that I, THoMAs F. DWYER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hinges for VVindow-Shutters, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to hinges for windowshutters; and the object thereof is to provide an improved hinge of this class having means whereby the shutter may be conveniently locked in an open position, thelocking being automatic and the unlocking done by hand; and with this and other objects in view the invention consists in a hinge for window-shutters constructed as hereinafter described and claimed.

The invention is fully disclosed in. thefollowing specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which I Figure l is a perspective view of the hinge detached and showing the parts of the hinge in the position they occupy when the shutter is locked in an open position; Fig. 2, a plan view of the hinge, showing the shutter locked in an open position and showing also a part of a window frame and shutter in section; and Fig. 3, a view looking in the direction of the arrow .1; of Fig. 1.

In the drawings forming part of this specification I have shown at a a part of the wall of a building and at a a part of a windowframe, and at a I have shown a part of a window-shutter, and in the practice of my invention I provide a shutter-hinge comprising two part-s b and c. The part b of the hinge consists in the form of construction shown of a plate 7), adapted to be secured to the window-frame a and anarm 6 which projects at right angles thereto and which is flat and oblong in vertical section and provided at its end with a downwardly-directed cam-plate 6*, which extends parallel with the window and parallel with the shutter when the latter is in a closed position and the highest part of which is in the form of construction shown slightly below the highest part of the arm 6".

The part c of the hinge is the part which in practice is secured to the shutter a", and said part consists of a flat metal plate provided with an arm 0 which projects at an angle to the plate and to the shutter when the parts are connected of about forty-five degrees, and the arm '0 is provided with a tubular head 0 through which is passed a pintle-pin 71', con nected with the arm 6 The angle-arm 0 of the hinge member 0 is provided with a yoke-shaped bracketd, which is secured thereto and provided with parallel jaws 6Z2, through which is passed a verticallymovable lock-pin e, that part of which between the jaws (5 is provided with a loop, collar, or other stop 0 which limits the vertical movement of said pin. In the form of construction shown the yoke-shaped bracket cl is secured to the arm 0 in such a manner that the top of said bracket is slightly above said arm, while the bottom thereof is slightly above the bottom edge of said arm, and in the operation of the hinge when the shutter a is swung open the lower end of the pinestrikes the top surface of the cam-plate b" and moves upwardly, and when the shutter is entirely open, as shown in Fig. 3, said pin drops down back of the arm 5 as is also shown in said figure, and the shutter is locked in an open position. WVhen it is desired to close the shutter, the pin 6 is raised and the shutter swung inwardly in the usual manner.

My invention is not limited to the exact construction of the separate parts of the hinge or of \he yoke-shaped bracket (Z, and the angular portion of the arm 0 may be provided with the jaws d in any desired manner, and various other changes in and modifications of the construction described may be made without departing from the spirit of my invention.

In Fig. 2 of the drawings the shutter a is shown in a closed position in dotted lines and in an open position in full lines, and the separate parts of the hinge are also shown or indicated in both of said positions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A shutter-hinge, comprising two parts, one of which is adapted to be secured to a windowframe and the other to a shutter, that part which is adapted to be secured to the windowframe being provided with an arm having at its end a downwardly-inclined cam-plate which projects laterally therefrom, and a pintle-pin adjacent to said cam-plate, and that part of the hinge which is adapted to be secured to the shutter being provided with an angular vided with projecting jaws, and a verticallymovable lock-pin passed through said jaws and the lower end of which is adapted to operate in connection with said cam-plate, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 6th day of August, 1904:.

THOMAS F. DVVYER.
